Omnibus Magnetic Tape Options

This document provides technical specifications and programming information for various peripheral options for the PDP-8/E computer system, specifically focusing on magnetic tape and laboratory data acquisition peripherals.

Magnetic Tape Options:

• DECtape (TD8-E/TC08): A fixed-address magnetic tape system used for auxiliary storage. The document details configurations (using TU56 transports), system architecture, tape formatting (mark/timing tracks), and provides a comprehensive list of IOT instructions for programming the TC08 and TD8-E controllers.
• DECmagtape (TM8-E/TC58/TU10): A system for industry-compatible magnetic tape. It covers master/slave configurations (using TU10 transports), data transfer via single-cycle data breaks, and provides detailed IOT instruction sets and status register bit definitions for programming the TM8-E and TC58 controllers.

Laboratory Peripherals:

• AD8-EA Analog-to-Digital Converter: A 10-bit converter for the PDP-8/E. It includes specifications, programming instructions, and examples for various modes (normal, clock, and fast sample).
• AM8-EA 8-Channel Analog Multiplexer: Designed to expand the AD8-EA capability to 16 channels, including programming and operation modes.
• DR8-EA 12-Channel Buffered Digital I/O: A module for controlling external digital circuits or accepting digital inputs, with details on jumper-selectable device codes and programming.
• DB8-E Interprocessor Buffer: Allows data transfer between two PDP-8/E computers or between one computer and user-designed logic.
• Miscellaneous: Brief mentions of the Laboratory Mounting Panel (H945) and various modules/panels for real-time clocks and oscilloscope interfaces.

Disk Systems:

• RK8 Disk System: Provides modular, random-access mass storage using removable cartridges. Includes technical specifications, programming, and status register details.
• DF32-D and RF08/RS08 Disk Systems: Bulk-storage disk systems for the PDP-8/E. The document covers their respective capacities, data transfer methods (3-cycle data break), and provides specific programming instruction sets for each.
